=====Data Connections =====

See [[opencpn:opencpn_user_manual:faq#flatpak_data_port_connection_issues|Data Port Connection Issues]]

There are some things related to serial data ports, in particular on Flatpak.

  - There is a bug: https://github.com/OpenCPN/OpenCPN/issues/2528-
  - The port must be accessible. See https://github.com/OpenCPN/OpenCPN/b...NUX_DEVICES.md, the chapter on Device Access.
  - Even if the port is accessible it might not be visible in the UI. Two solutions.
  - The first is to write the name of the device, perhaps something like /dev/ttyUSB0 in the GUI (one don't have to select from the drop-down list, it's possible to enter the device name as well)
  - The second is to create a device link as described in https://github.com/OpenCPN/OpenCPN/b...NUX_DEVICES.md, the chapter on Fixed Device Names. Such links are visible in the GUI

A new point Flatpak point fix has been pushed for this issue. To update the Flatpak installation do
Code:

  $ flatpak update org.openpcn.OpenCPN

Note that despite the patch, devices must still be accessible as described in https://github.com/OpenCPN/OpenCPN/b...NUX_DEVICES.md
